Abstract (en)

[origin: WO2005109387A2] Within a display system (10) that has pixel arrays displayed during first and second intervals, visible noise reduction occurs by confining the noise to one interval by combining the fractional part of each first interval pixel with the fractional part of at least one second interval pixel. If the combined fractional parts has a value of at least unity, the integer part of the at least one second interval pixel increases by unity while its fractional part becomes zero. The combination of the fractional parts less unity replaces the fractional part of the first interval pixel. While the combined value of fractional parts remains below unity, the combined value replaces the fractional part of the second interval pixel and the fractional part of the first interval pixel becomes zero. In this way, light intensity shifting occurs between intervals so that no noticeable brightness variation occurs across the overall scene.
